What determines the relative amounts of reactants and products at equilibrium?
Show answer
The conditions of the reaction (e.g. temperature, pressure, concentration).
How does a system at equilibrium respond to a change in conditions?
Show answer
It shifts so as to counteract the change.
If a system at equilibrium has a condition changed, the system responds to ? the change.
Show answer
counteract
Which principle predicts the effect of changing conditions on a system at equilibrium?
Show answer
Le Chatelier's Principle.
State Le Chatelier's Principle.
Show answer
If a change is made to the conditions of a system at equilibrium, the position of equilibrium shifts to counteract that change.
The effects of changing conditions on an equilibrium can be predicted using ? Principle.
Show answer
Le Chatelier's
What kind of predictions does Le Chatelier's Principle allow about an equilibrium?
Show answer
Qualitative predictions — the direction the equilibrium shifts, not the exact amounts.
